The head of the Israel Defense Forces said Tuesday that “the campaign against Iran is not over” as a ceasefire between the two countries went into effect. President Donald Trump also vowed that Israel will not attack Iran and told Israel to bring its pilots home.

The fragile ceasefire between Israel and Iran appears to be holding after a rocky start, giving rise to cautious hope it could lead to a longer term peace agreement even as Tehran insisted it would not give up its nuclear program.

Each side claimed victory on Tuesday after 12 days of war, which the US joined with airstrikes in support of Israel to take out Iran's uranium-enrichment facilities.
